KVM: arm64: nv: Handle CPACR_EL1 traps
Handle CPACR_EL1 accesses when running a VHE guest. In order to
limit the cost of the emulation, implement it ass a shallow exit.
In the other cases:
- this is a nVHE L1 which will write to memory, and we don't trap
- this is a L2 guest:
* the L1 has CPTR_EL2.TCPAC==0, and the L2 has direct register
access
* the L1 has CPTR_EL2.TCPAC==1, and the L2 will trap, but the
handling is defered to the general handling for forwarding
